WATER COOLER FOR LOCOMOTIVES.

Application filed December 29, 1921. Serial No. 525,648.

To all whom it may concern.

Be it known thatI, REINHARD KLINGEL- HOFFER, 'residing at Werden-on-the-Ruhr, Germany, a citizen of the German Republie, have invented a certain new and useful Improvement in WVater Coolers for Locomotives, of which the following is a specification. 1

This invention relates to steam locomotives with a condenser and a reflux cooler composed of separate cooling cells and fitted with a blower delivering the required cooling air into said cells. The object of the invention is, to enable the requisite cooling of the hot waterflowing out of the condenser of the locomotive to be performed with a minimum expenditure of power.

One form of the invention is illustrated in the accompanying drawing, by way of example, in which: i

Fig. l is a longitudinal section through the reflux cooler located on the tender,

Fig. 2 is a horizontal section taken on the line 22 of Fig. 1, and I I Fig. 3 is a section taken on line 83 of Fig; 2.

In order to attain the object of the invention, it is necessary:

First, to make the entire surface area of the coolingcells as large as possible, and,

Second, to have the GlOSS-SGClLlOIlfil'flOW areaof the blower large and the peripheral velocity of the blower wheel low.

Accordingly the cooling cells are arranged; in a plurality of stacks and the blower'is through thefilllng mater al-and the bottoms placed in the middle between the cell's.

The reflux cooler is separated into separate cooling cells by means of substantially horizontal walls m and vertical walls K. The individual cooling cells are provided in the usual manner with a perforated bottom 6 and partly filled witha suitable filling material which presents a large surface but slight resistance to 'the water flow. A tube a is in connection with the condenser of the locomotive from which horizontal branchesv a lead into each of the cells 6. Inside the cells small bore tubes a are connected to the branches a. The purpose of the tubes a is to spray the water to be cooled over the stuffing mass.

In the center of the reflux cooler on either side of its central longitudinal plane a chamber 0 is provided in the center. of which a shutter h whiclrmay be adjustably mounted as suggested in Fig. 1 (see righthand end cell second from the top). Theehamber c is narrowed at both ends in such a manner-- that air from the blower ef is supplied to all of the apertures g withapproximateuniformity. The reflux cooler is surrounded by a shell Rwhich has at its top an openingr for the discharge of the cooling air.- The cells Z2 with the exception of the lowest, are Y so arranged longitudinally of the reflux cooler, that on each side a space n exists betweenthe shell and the cells The width of thesespaces increases towards the opening r in such a manner that the effect of the in- 7 coming cooling air is approximately uniform in all parts ofsaid spaces. A chamber d communicates with the interior of the shell R by means of anopening W, and a pipe s (Fig 1) leads from chamber d to the corn denser. V

The operation is as follows: The hot watercoming from the condenser through the pipe a, Fig. 1, is conducted through the system of pipes a a to the separate cooling cells b and trickles down 72 upon the partitions m, from which it flows into the space 0 and is discharged through the opening 1 into the receptacle (Z, Fig. 1.

Each: cooling cell communicates cells I) are therefore arranged in parallel with respect to the cooling air and to the cooling water. In its path through the openings n, the air, saturated with steam and drops of water, must frequently change its direction, so that the water is deposited on.

the walls and flows back, whereby loss of water is avoided.

Claims:

1. A reflux cooler for locomotives provided with a condenser, said cooler being formed with a plurality of sections, vertically disposed walls forming said sections, said sections being divided into separate cooling cells, and approximately horizontal partitions forming said separate cooling cells.

2. A reflux cooler for locomotives provided with a condenser, said cooler being formed with a plurality of sections, vertically disposed walls forming said sections and approximately horizontal partitions dividing said sections into separate coo-ling cells, means for conducting cooling air and water to be cooled into said cells, said cells being arranged in parallel for the'cooling air and for the water to be cooled.

3. A reflux cooler for locomotives provided with a condenser, said cooler being provided with a plurality of sections, a plurality of separate cooling cells contained in said sections, said sections being formed with a space therebetween and a blower disposed in the space between these of said sections which are farthest apart from each other.

4;. A reflux cooler for locomotives provided with a condenser, said cooler being formed with a plurality of sections, a plurality of separate cooling cells contained in said sections, said sections being formed with a space therebetween, a blower disposed centrally of said space, said space communicating with said cooling cells, the cross-section of said space decreasing rrom said blower toward said cells so that the velocity of the blast of air is substantially equal at every cross-section.

5. A reflux cooler for locomotives provided with a condenser, said cooler being formed with a plurality of sections and separate cooling cells, said sections being disposed so as to provide a space therebetween, a blower disposed centrally of said space, said space communicating with said cooling cells, said cells being provided with inlet openings communicating, with said space, adjustable closure elements associated with said openings, the cross-section of said space decreasing from said blower toward said cells so that the velocity of the blast of air is substantially equal at every crosssection.

6. A reflux cooler for locomotives provided with a condenser, said cooler having a plurality of sections, each section containing a plurality of separate cooling cells, a blower disposed centrally of said sections and furnishing air to said cooling cells, outlet passages disposed on the outer side of said sections and communicating with said cells, said outlet passages having a tortuous course whereby water carried by the air passing through said passages will be separated therefrom. I

7. A reflux cooler for locomotives provided with a condenser, said cooler having a plurality of sections, each section containing a plurality of separate cooling cells, a blower disposed centrally of said sections and furnishing air to said cooling cells, outlet passages disposed on the outer side of said sections and communicating with said cells, said outlet passages having a tortuous course whereby water carried by the air passing through said passages will be separated therefrom, the cross-section of said passages increasing toward the outlet opening thereof so that the velocity of the air is substantially equal at every cross-section,

8. A reflux; cooler for locomotives provided with a condenser, said cooler having a plurality of sections, each section containing a plurality of separate cooling cells, said sections being disposed so as to provide a central space therebetween, a blower disposed in said space and air inlet passages for said blower disposed concentric with the shaft of the blower.
